TECHNICAL FIELD

[0001] The present invention relates to an apparatus, and a method therefor, which is communicatively connected via a network to a portable terminal carried by a user and to a plurality of printing apparatuses provided at various locations, and which outputs, in response to a data print request from the portable terminal, data associated with the data print request to one of the printing apparatuses. More specifically, it relates to a data output control apparatus which is suitable for allowing detailed information on a network to be readily obtained.

BACKGROUND ART

[0002] In recent years, information on the Internet is readily available anywhere using, for example, i-mode™ provided by NTT Mobile Communications Network, Inc. (NTT DoCoMo).

[0003] However, although such a portable terminal allows information on the Internet to be readily obtained anywhere, because the construction of display means is simplified for purposes such as reducing the size of and saving energy for the portable terminal, the displayed information is rather simplified compared with a display on an ordinary personal computer, hardly achieving an information service which is fully satisfactory for the user.

[0004] Accordingly, in order to provide detailed information while continuing to reduce the size of and save energy for the portable terminal, an arrangement can be proposed in which, by a combination of a portable terminal and a printing apparatus, rough information is displayed on the portable terminal while detailed information is printed by the printing apparatus. However, the arrangement using the combination of portable terminal and printing apparatus faces several technical problems which must be solved.

[0005] For example, since the printing apparatus is large in size and is hard to be carried with the portable terminal, in order to print the detailed information, ordinarily, the printing apparatus will be used provided at home or at office. However, use of a fixed, particular printing apparatus would hardly allow information to be readily obtained anywhere. In order to achieve this, it is required that either the size of the printing apparatus be reduced to such an extent as to allow carrying it, or an arbitrary printing apparatus be allowed to be used. The former is not feasible because it is technically very hard to achieve at this stage. The latter is not feasible either because each printing apparatus requires a unique driver, thus requiring that the portable terminal be embedded with drivers for each of the printing apparatuses to be used.

[0006] Accordingly, the present invention has been made in view of the problems yet to be solved by the conventional art, and an object thereof is to provide a data output control apparatus which is suitable for allowing detailed information on a network to be readily obtained.

BEST MODE FOR CARRYING OUT THE INVENTION

[0053] An embodiment of the present invention will be described below with reference to the drawings. FIG. 3 to FIG. 7 are diagrams showing a data output control apparatus according to the embodiment of the present invention.

[0054] In this embodiment, as shown in FIG. 3, the data output control apparatus according to the present invention is applied to a case where, by a portable terminal 100 carried by a user, such as a cellular phone, and a data output control terminal 300 communicatively connected via the Internet 400 to printing apparatuses PR₁ to PR_(n) respectively provided at a plurality of shops S₁ to S_(n) existing at various locations, a service provider, in response to a data print request from the user, provides a service wherein data associated with the data print request received from one of WWW (World Wide Web) servers DS₁ to DS_(m) is obtained and output to one of the printing apparatuses PR₁ to PR_(n). For ease in understanding the present invention, only a single portable terminal 100 is shown; however, a plurality of different types of the portable terminal 100 is allowed to be connected to the Internet 400.

[0055] First, the configuration of a network system in which the data output control apparatus according to the present invention is applied will be described with reference to FIG. 3. FIG. 3 is a block diagram showing the configuration of the network system in which the data output control apparatus according to the present invention is applied.

[0056] As shown in FIG. 3, a junction station 210 which relays communications between the portable terminal 100 and the Internet 400, the printing apparatuses PR₁ to PR_(n) for printing data, the WWW servers DS₁ to DS_(m) on which data is stored, the data output control apparatus 300 for obtaining data associated with a data print request from one of the WWW servers DS₁ to DS_(m) and outputting the data to one of the printing apparatuses PR₁ to PR_(n), and data-format-conversion terminals CS₁ to CS₁ for converting the data obtained by the data output control terminal 300 into data which can be printed by the printing apparatuses PR₁ to PR_(n), are connected to the Internet 400.

[0057] A plurality of base stations 200 which communicates with the portable terminal 100 by wireless is connected to the junction station 210. When the portable terminal 100 is connected to the Internet 400, the junction station 210 serves on behalf of the portable terminal 100 as a terminal on the Internet 400, wherein data which is received from the portable terminal 100 via a base station 200 is transmitted to a designated terminal via the Internet 400, and wherein data on the designated terminal connected to the Internet 400 is transmitted to the portable terminal 100 via the base station 200. The portable terminal 100 simultaneously communicates with at least three base stations 200, and the junction station 210 obtains the difference in the amount of time taken for radio waves from the portable terminal 100 to reach each of the base stations 200, so that the position of the portable terminal 100 can be determined based on the time difference obtained.

[0058] Each of the WWW servers DS₁ to DS_(m) comprises a storage unit which stores display data for display on the portable terminal 100 and print data for printing by the printing apparatuses PR₁ to PR_(n) corresponding to the display data, and a request processing unit which, in response to a request from a terminal connected to the Internet 400, such as the junction station 210 and the data output control terminal 300, transmits the data in the storage unit to the terminal.

[0059] The request processing unit, the functionality thereof being implemented by a CPU which is not shown, executing a program which is stored in an external storage device, etc., transmits either the display data or the print data in the storage unit in response to a data transmission request from an external terminal (the portable terminal 100, the data output control terminal 300, etc.). Which of the display data or the print data is transmitted is determined according to a URL included in the data transmission request. The storage unit stores, as the print data, various files of, for example, text data, still picture data, sound data, motion picture data in MPEG, etc., 3D image data in VRML, etc., or program data in JAVA etc., and HTML (Hyper Text Markup Language) files.

[0060] The data-format-conversion terminals CS₁ to CS₁ are terminals for executing data-format-conversion processes in which the data obtained by the data output control terminal 300 is converted into data which can be printed by the printing apparatuses PR₁ to PR_(n). According to the transmission load of the Internet 400 or the processing load of the data-format-conversion terminals CS, one or more of the data-format-conversion terminals CS₁ to CS₁ is selected so that the data-format-conversion processes will be executed on the selected data-format-conversion terminals CS. More specifically, in the order for the transmission load of the Internet 400 or the processing load of the data-format-conversion terminals CS to be low, one or more of the data-format-conversion terminals CS₁ to CS₁ is selected as required for the data-format-conversion processes.

[0061] Each of the data-format-conversion terminals CS on which the data-format-conversion processes are executed receives from the data output control terminal 300 a data-format-conversion request and the data to be converted; and by the data-format-conversion processes, of the data obtained by the data output control terminal 300, converts data of a predetermined format to data which can be printed by the corresponding printing apparatuses PR₁ to PR_(n); and transmits the converted data to the data output control terminal 300.

[0062] For example, if the format conversion processes are executed on the data-format-conversion terminals CS₁ to CS₃, the data-format-conversion terminal CS₁ converts, of the data obtained by the data output control terminal 300, data in a predetermined format A (e.g. HTML format) into data which can be printed by the printing apparatuses PR₁ to PR₅; the data-format-conversion terminal CS₂ converts, of the data obtained by the data output control terminal 300, data in a predetermined format B (e.g. JPEG format) into data which can be printed by the printing apparatuses PR₆ to PR₁₀; the data-format-conversion terminal CS₃ converts, of the data obtained by the data output control terminal 300, data in a predetermined format C (e.g. WORD™ document format) into data which can be printed by the printing apparatuses PR₁₁ to PR₁₅; and so forth. In this case, apparently, the printing apparatuses PR₁ to PR₅ serve as apparatuses dedicated for printing data in the predetermined data format A, the printing apparatuses PR₆ to PR₁₀ serve as apparatuses dedicated for printing data in the predetermined data format B, and the printing apparatuses PR₁₁ to PR₁₅ serve as apparatuses dedicated for printing data in the predetermined data format C.

[0063] In addition to converting the data obtained by the data output control terminal 300, each of the data-format-conversion terminals CS on which the dataformat-conversion processes are executed, in accordance with display capabilities (the number of lines to be displayed, display resolution, etc.) of each type of the portable terminal 100, generates preview data which can be displayed on the portable terminal 100, i.e., an image of the data obtained by the data output control terminal 300 as printed by a printing apparatus PR, and the preview data generated is transmitted to the data output control terminal 300.

[0064] Thus, the data output control terminal 300 transmits the data-format-conversion request and the data obtained from a WWW server DS to the data-format-conversion terminal CS corresponding to the printing apparatus PR by which the data associated with the data print request is to be printed, and as a response thereto, receives the data which can be printed by the printing apparatus PR by which the data is to be printed and the preview data.

[0065] Next, the construction of the portable terminal 100 will be described with reference to FIG. 4. FIG. 4 is a block diagram showing the construction of the portable terminal 100.

[0066] As shown in FIG. 4, the portable terminal 100 comprises a CPU 30 which controls operations and the overall system based on a control program; a ROM 32 which stores, in advance, the control programs for the CPU 30, etc. in a predetermined area; a RAM 34 which stores data read from the ROM 32, etc. and operation results required in the course of the operations by the CPU 30; an LCDC (Liquid Crystal Display Controller) 36 for converting data stored in a specific area of the RAM 34 into an image signal and outputting the image signal to an LCD (Liquid Crystal Display) 44; and an I/F 38 which intermediates data input from and data output to external apparatuses; the components being mutually connected via a bus 39, which is a signal line for transferring data, so as to allow exchange of data.

[0067] As the external apparatuses, a key panel 40 which serves as a human interface and which allows input of data using a plurality of keys, a transmission and reception control apparatus 42 for communicating with the base stations 200 by wireless, the LCD 44 on which an image is displayed based on the image signal, and a positioning apparatus 46 for determining the location of the current position are connected to the I/F 38.

[0068] The ROM 32 stores, in addition to the control program for the CPU 30, authentication data for determining whether or not the user is a legitimate user of the print service provided by the data output control terminal 300.

[0069] The RAM 34 includes, as the specific area, a VRAM 35 for storing the display data for display on the LCD 44, the VRAM 35 allowing independent accesses from the CPU 30 and the LCDC 36.

[0070] The LCDC 36 sequentially reads, at a predetermined cycle, the display data stored in the VRAM 35 from the start address, converts the display data which has been read into an image signal, and outputs the image signal to the LCD 44.

[0071] The positioning apparatus 46 employs GPS (Global Positioning System), etc., to receive time signals from orbiting satellites which transmit the time signals indicating the current time, determining the location of the current position based on the time difference indicated by the time signals and the orbits of the orbital satellites.

[0072] The CPU 30 is constituted of a microprocessing unit MPU, etc., and activates a predetermined program stored in a predetermined area of the ROM 32 to execute, according to the program, data print request processes shown in the flowchart of FIG. 5. FIG. 5 is a flowchart showing the data print request processes.

[0073] In the data printing request processes, by issuing a data print request, a request is made that data on a WWW server DS designated by the user be printed by one of the printing apparatuses PR₁ to PR_(n), and when executed by the CPU 30, as shown in FIG. 5, initially moves to step S100.

[0074] In step S100, in accordance with an input by the user via the key panel 40, it is determined whether or not a data print request has been made. If it is determined that there is a data print request (Yes), the processes move to step S102, in which the positioning apparatus 46 determines the location of the current position. The processes then move to step S104, in which various information associated with printing is input via the key panel 40. As the various information associated with printing, the user inputs, for example, a URL which uniquely identifies the location of the WWW server DS on the Internet, which stores the print data to be printed, a desired service area which is the approximate location where the service of output data is desired, print specifications of the printing apparatus PR, such as the size of paper, a designation of color/monochrome, printing resolution, and printing speed, a data format of the print data to be printed, and when a printing apparatus PR is to be directly specified, a printing apparatus ID for identifying the printing apparatus PR. All of these input items are not necessarily required, but are selectively input according to user requirements. As for the URL of the WWW server DS, however, unless otherwise specified, the URL of the WWW server DS being browsed at that time by the user with the portable terminal 100 is automatically input.

[0075] Next, the processes move to step S106, in which data to be included in the data print request is generated based on the various information associated with printing which has been input. More specifically, the data to be included in the data print request is generated with the location of the current position, determined in step S102, as portable-terminal-position data for identifying the location of the current position; the URL of the WWW server DS as printing target storage location data indicating the URL; the desired service area, if it is input, as desired service area data indicating the desired service area; the print specifications of the printing apparatus PR, if they are input, as print specification data indicating the print specifications; the data format, if it is input, as print format data indicating the data format; and the printing apparatus ID of the printing apparatus PR, if it is input, as printing-apparatus identification data indicating the printing apparatus ID.

[0076] Next, the processes move to step S108, in which the data print request is transmitted to the data output control terminal 300. The processes then move to step S110, in which, as a response thereto, printing-apparatus candidate data listing several candidates of the printing apparatus PR, which are presumably the most suitable for the user to receive the service of output data, is received from the data output control terminal 300, and based on the printing-apparatus candidate data received, the listed candidates of the printing apparatus PR are displayed on the LCD 44. The processes then move to step S112.

[0077] In step S112, it is determined whether or not the printing apparatus which is desired for the service of output data is included in the candidates of the printing apparatus PR displayed on the LCD 44. If it is determined, by an input via the key panel 40 selecting one of the candidates of the printing apparatus PR displayed on the LCD 44, that the printing apparatus PR which is desired for the service of output data is included (Yes), the processes move to step S114.

[0078] In step S114, a determination signal, which indicates that the printing apparatus PR has been determined, is transmitted to the data output control terminal 300. The processes then move to step S116, in which as a first response to the transmission of the determination signal, printing-apparatus information, which is detailed information regarding the printing apparatus PR determined (location, print specifications, etc. of the printing apparatus PR) is received from the data output control terminal 300, and based on the printing-apparatus information received, the detailed information regarding the printing apparatus PR is displayed on the LCD 44. The processes then move to step S118.

[0079] In step S118, as a second response to the transmission of the determination signal, guide data, indicating guide information (route information, map information, etc.) for guiding the user from the position of the portable terminal 100 to the position where the determined printing apparatus PR is provided, is received from the data output control terminal 300, and based on the guide data received, the guide information is displayed on the LCD 44. The processes then move to step S120, in which as a third response to the transmission of the determination signal, preview data is received from the data output control terminal 300, and based on the received preview data, an image of a print by the determined printing apparatus PR is displayed on the LCD 44. The processes then move to step S122.

[0080] In step S122, it is determined whether or not the print data to be printed is actually the image displayed on the LCD 44. If it is determined that the image displayed on the LCD 44 is correct (Yes) by an input via the key panel 40 which selects that the image displayed on the LCD 44 is correct, the processes move to step S124. At this time, if the preview data is composed of a plurality of data, the part thereof which is desired to be printed can be specified.

[0081] In step S124, a data print execution request is transmitted to the data output control terminal 300. The processes then move to step S126, in which the authentication data in the ROM 32 is transmitted to the data output control terminal 300. The processes then move to step S128, in which as a response thereto, a message is received from the data output control terminal 300, and the received message is displayed on the LCD 44. The processes then move to step S130, in which it is determined whether or not a completion signal, which indicates completion of the data print, has been received from the data output control terminal 300. If it is determined that the completion signal has been received (Yes), the series of processes is exited; however, if it is determined otherwise (No), step S128 is repeated until the completion signal is received.

[0082] On the other hand, if it is determined in step S122 that the image displayed on the LCD 44 is wrong (No) according to an input via the key panel 40 which selects that the image displayed on the LCD 44 is wrong, the processes move to step S132, in which a halt signal, which is a request for halting the data print, is transmitted to the data output control terminal 300. The series of processes is then exited.

[0083] On the other hand, if it is determined in step S112, according to an input via the key panel 40 which selects the desired printing apparatus is not included in the candidates of the printing apparatus PR displayed on the LCD 44, that the printing apparatus PR which is desired for the service of output data is not included (No), the processes move to step S134, in which a retry signal, which is a request to search again for the printing apparatus PR which is presumably the most suitable for receiving the service of output data, is transmitted to the data output control terminal 300. The processes then move to step S104.

[0084] On the other hand, if it is determined in step S100 that there is no data print request from the user (No), the processes wait in step S100 until a data print request is issued.

[0085] Next, the construction of the data output control terminal 300 will be described with reference to FIG. 6. FIG. 6 is a block diagram showing the construction of the data output control terminal 300.

[0086] The data output control terminal 300 obtains data associated with a data print request from the portable terminal 100, selects one of the printing apparatuses PR₁ to PR_(n) by which the data is to be printed, and outputs the data obtained to the selected printing apparatus PR. As shown in FIG. 6, the data output control terminal 300 comprises a CPU 50 which controls operations and the overall system based on a control program; a ROM 52 which stores, in advance, the control program for the CPU 50, etc. in a predetermined area; a RAM 54 which stores data which has been read from the ROM 52, etc. and operation results required in the course of the operations by the CPU 50; a CRTC 56 for converting the data stored in a specific area of the RAM 54 into an image signal and outputting the image signal; and an I/F which intermediates data input from and data output to external apparatuses; the components being mutually connected via a bus 59, which is a signal line for transferring data, so as to allow exchange of data.

[0087] As the external apparatuses, an input apparatus 60 comprising a keyboard, a mouse, etc., which serves as a human interface and which allows input of data, a storage apparatus 62 which stores data, tables, etc. as files, a display apparatus 64 on which an image is displayed based on the image signal, and a signal line for connecting to the Internet 400 are connected to the I/F 58.

[0088] The RAM 54 includes, as the specific area, a VRAM 55 for storing the display data for display on the display apparatus 64, the VRAM 55 allowing independent accesses from the CPU 50 and the CRTC 56.

[0089] The CRTC 56 sequentially reads, at a predetermined cycle, the display data stored in the VRAM 55 from the start address, converts the display data which has been read into an image signal, and outputs the image signal to the display apparatus 64.

[0090] The storage apparatus 62 stores printing-apparatus information regarding the printing apparatuses PR, which is required for selecting one of the printing apparatuses PR₁ to PR_(n) by which data is to be printed. The printing-apparatus information is configured by registering, for each of the printing apparatuses PR₁ to PR_(n), printing apparatus position data for identifying the location of the printing apparatus PR, print format data indicating the data format which can be converted by the data-format-conversion terminal CS corresponding to the printing apparatus PR (i.e., a data format which allows printing by the printing apparatus PR), print specification data indicating the print specifications of the printing apparatus PR, and printing-apparatus identification data indicating the printing apparatus ID.

[0091] The CPU 50 includes a microprocessing unit MPU, etc., and activates a predetermined program stored in a predetermined area of the ROM 52 to execute, according to the program, data output control processes shown in the flowchart of FIG. 7. FIG. 7 is a flowchart showing the data output control processes.

[0092] The data output control processes obtain, from a WWW server DS, print data associated with a data print request from the portable terminal 100, selects one of the printing apparatuses PR, which is presumably the most suitable for the user of the portable terminal 100 to receive the service of output data, and outputs the print data obtained to the selected printing apparatus PR, and when executed by the CPU 50, as shown in FIG. 7, initially moves to step S200.

[0093] In step S200, it is determined whether or not the data print request has been received from the portable terminal 100. If it is determined that the data print request has been received (Yes), the processes move to step S202, in which data included in the received data print request (including at least the portable-terminal-position data and the print target storage location data) is obtained. The processes then move to step S204, in which a printing apparatus PR which is presumably the most suitable for the user of the portable terminal 100 to receive the service of output data is selected.

[0094] More specifically, in step S204, a search is performed on the printing apparatus position data in the storage apparatus 62 based on the portable-terminal-position data obtained, selecting several printing apparatuses PR which are presumably nearest, in terms of distance or time, with reference to the position of the portable terminal 100. If desired service area data is included in the data print request, a search is performed on the printing apparatus position data in the storage apparatus 62 based on the desired service area data, selecting all the printing apparatuses PR in the area identified by the desired service area data. If print specification data is included in the data print request, a search is performed on the print specification data in the storage apparatus 62 based on the obtained print specification data, selecting all the printing apparatuses PR which comply with the print specification data.

[0095] If print format data is included in the data print request, a search is performed on the print format data in the storage apparatus 62 based on the print format data obtained, selecting all the printing apparatuses PR which comply with the print format data. If printing-apparatus identification data is included in the data print request, a search is performed on the printing-apparatus identification data in the storage apparatus 62 based on the obtained printing-apparatus identification data, selecting a printing apparatus PR corresponding to the printing-apparatus identification data. If these data are compositely included in the data print request, a search is performed based on each of the data. If the desired service area data is included, and the position identified by the portable-terminal-position data is not included in the area identified by the desired service area data, a search based on the portable-terminal-position data is not performed. If the printing-apparatus identification data is included, a search based on other data is not performed.

[0096] Next, in step S204, printing-apparatus candidate data which lists the printing apparatuses PR selected in step S202 is generated, and the printing-apparatus candidate data generated is transmitted to the portable terminal 100. The processes then move to step S208.

[0097] In step S208, it is determined whether or not the determination signal has been received from the portable terminal 100. If it is determined that the determination signal has been received (Yes), the processes move to step S210, in which print data is obtained from the WWW server DS identified by the URL included in the obtained print target storage location data. The processes then move to step S211, in which the print data obtained is transmitted to the data-format-conversion terminal CS which allows conversion of the print data and which corresponds to the determined printing apparatus PR, and as a response thereto, obtains from the data-format-conversion terminal CS data which can be printed by the determined printing apparatus PR and preview data. The processes then move to step S212.

[0098] In step S212, printing-apparatus information regarding the determined printing apparatus is read from the storage apparatus 62, and the printing-apparatus information which has been read is transmitted to the portable terminal 100. The processes then move to step S214, in which guide data regarding the determined printing apparatus PR is generated, and the generated guide data is transmitted to the portable terminal 100. The processes then move to step S216, in which the preview data is transmitted to the portable terminal 100. The processes then move to step S218.

[0099] In step S218, it is determined whether or not a data print execution request has been received from the portable terminal 100. If it is determined that the data print request has been received (Yes), the processes move to step S220, in which authentication data is received from the portable terminal 100. The processes then move to step S222, in which authentication processes are executed, based on the received authentication data, in order to determine whether or not the user of the portable terminal 100 is a legitimate user of the print service provided by the data output control terminal 300. The processes then move to step S224.

[0100] In step S224, as a result of the authentication processes in step S222, in which it is determined whether or not the user of the portable terminal 100 is a legitimate user, if the user is determined as a legitimate user (Yes), the processes move to step S226, in which the data which can be printed by the determined printing apparatus PR is transmitted to the printing apparatus PR. The processes then move to step S228, in which billing processes are executed in which billing is executed in accordance with the result of usage by the portable terminal 100 of the print service provided by the data output control terminal 300.

[0101] In step S228, more specifically, the call charge of the portable terminal 100 (e.g. call charge on a minute basis) is calculated, and as the result of use by the portable terminal 100, with reference to the charge calculation definition table which defines the service charge as the price of the print service with regard to, for example, the volume of the data obtained, the number of prints by the printing apparatus PR, and the print specifications of the printing apparatus PR, the service charge in accordance with the result of use by the portable terminal 100 is calculated. The calculated service charge is added to the call charge, the added total sum being stored as the charge amount to the user of the portable terminal 100.

[0102] Next, the processes move to step S230, in which a billing message, which indicates the service charge calculated in the billing processes of step S228 is transmitted to the portable terminal 100. The processes then move to step S232, in which a completion message, which indicates completion of the data print, is transmitted to the portable terminal 100. The series of processes is then exited.

[0103] On the other hand, if it is determined in step S224 that the user of the portable terminal 100 is not a legitimate user (No), the processes move to step S236, in which a message indicating that the user is an illegitimate user is transmitted to the portable terminal 100. The series of processes is then exited.

[0104] On the other hand, if it is determined in step S218 that the data print execution request has not been received from the portable terminal 100 (No), the processes move to step S238, in which it is determined whether or not the halt signal has been received from the portable terminal 100. If it is determined that the halt signal has been received (Yes), the series of processes is exited, but if otherwise (No), the processes move to step S218.

[0105] On the other hand, if it is determined in step S208 that the determination signal has not been received from the portable terminal 100 (No), the processes move to step S240, in which it is determined whether or not the retry signal has been received from the portable terminal 100. If it is determined that the retry signal has been received (Yes), the processes move to step S200, but if otherwise (No), the processes move to step S208.

[0106] On the other hand, if it is determined in step S200 that the data print request has not been received from the portable terminal 100 (No), the processes wait in step S200 until the data print request is received.

[0107] Next, the operation of the embodiment will be described.

[0108] First, when a legitimate user of the print service provided by the data output control terminal 300 operates the portable terminal 100 he carries, accessing, for example, the WWW server DS₁, display data on the WWW server DS₁ is displayed on the LCD 44. The description will be made by way of example in relation to a case where the user is to print detailed data of the data displayed on the LCD 44.

[0109] In order to print the desired data, the user initially inputs a data print request via the key panel 40.

[0110] On the portable terminal 100, when the data print request is input, through steps S100 and S102, the CPU 30 determines the location of the current position by the positioning apparatus 46, displaying on the LCD 44 a request for input of various information associated with printing. The user specifies and inputs, as the various information associated with printing, the URL of the WWW server DS₁ which is being browsed. Then, through steps S104 to S108, based on the various information associated with printing which has been input, portable-terminal-position data and print target storage location data are generated as data to be included in the data print request, and the data print request is transmitted to the data output control terminal 300.

[0111] Meanwhile, on the data-format-conversion terminals CS₁ to CS₁, one or more of the data-format-conversion terminals CS₁ to CS₁, which is required for the data-format-conversion processes, is selected in the order for the transmission load of the Internet 400 or the processing load of the data-format-conversion terminals CS to be low, the data-format-conversion processing being executed by the selected dataformat-conversion terminals.

[0112] Meanwhile, on the data output control terminal 300, when the data print request is received, through steps S200 to S204, the CPU 50 obtains the data (the portable-terminal-position data and print target storage location data) included in the received data print request, and performs a search on the print apparatus position data in the storage apparatus 62 based on the obtained portable-terminal-position data, selecting several printing apparatuses PR which are presumably nearest, in terms of distance or time, with reference to the position of the portable terminal 100. If the printing apparatuses PR₁ to PR₅ are selected, through step S206, printing-apparatus candidate data listing the printing apparatuses PR₁ to PR₅ is generated, and the generated printing-apparatus candidate data is transmitted to the portable terminal 100.

[0113] On the portable terminal 100, when the printing-apparatus candidate data is received, through step S110, based on the received printing-apparatus candidate data, the listed printing apparatuses PR₁ to PR₅ are displayed on the LCD 44. When the user inputs a selection of the printing apparatus PR₁, through steps S112 and S114, a determination signal indicating that the printing apparatus PR₁ has been determined is transmitted to the data output control terminal 300.

[0114] On the data output control terminal 300, when the determination signal is received, through steps S208 to S211, the print data is obtained from the WWW server DS₁ identified by the URL included in the obtained print target storage location data, and the obtained print data is transmitted to a data-format-conversion terminal CS (e.g. the data-format-conversion terminal CS₁) which allows conversion of the print data and which corresponds to the determined printing apparatus PR₁.

[0115] On the data-format-conversion terminal CS₁, when the print data is received, the received data is converted into data which can be printed by the printing apparatus PR₁. Also, preview data is generated in accordance with the display functionality of the portable terminal 100. The converted data which can be printed by the printing apparatus PR₁ and the preview data generated are transmitted to the data output control terminal 300.

[0116] On the data output control terminal 300, when the data which can be printed by the printing apparatus PR₁ and the preview data are received, through steps S212 to S216, printing-apparatus information regarding the determined printing apparatus PR₁ is read from the storage apparatus 62, and the printing-apparatus information which has been read is transmitted to the portable terminal 100. Also, guide data regarding the determined printing apparatus PR₁ is generated, and the guide data generated and the preview data received are transmitted to the portable terminal 100.

[0117] On the portable terminal 100, when the printing-apparatus information, the guide data, and the preview data are received, through steps S116 to S120, based on the received printing-apparatus information, detailed information regarding the printing apparatus PR is displayed on the LCD 44, and based on the received guide data, guide information from the position of the portable terminal 100 to the position where the printing apparatus PR₁ is disposed is displayed on the LCD 44, and based on the received preview data, an image of a print by the determined printing apparatus PR₁ is displayed on the LCD 44. When the user inputs via the key panel 40 a selection that the image displayed on the LCD 44 is correct for the display data to be printed, through steps S122 to S126, a data print execution request and the authentication data in the ROM 32 are transmitted to the data output control terminal 300.

[0118] On the data output control terminal 300, when the data print execution request and the authentication data are received, through steps S218 to S222, authentication processes are executed based on the received authentication data. Since the user is a legitimate user of the print service provided by the data output control terminal 300, through steps S224 to S234, the data which can be printed by the determined printing apparatus PR₁ is transmitted to the printing apparatus PR₁, the billing processes are executed, and a billing message, a completion message, and a completion signal are transmitted to the portable terminal 100.

[0119] On the portable terminal 100, when the billing message, the completion message, and the completion signal are received, through a repetition of steps S128 and S130, the billing message and the completion message are displayed on the LCD 44. Meanwhile, on the printing apparatus PR₁, when the data which can be printed by the printing apparatus PR₁ is received, printing is executed based on the received data.

[0120] When the completion message is displayed, the user visits the store S₁ where the printing apparatus PR₁ is provided with reference to the guide information displayed on the LCD 44, and receives the data printed by the printing apparatus PR₁. The service charge as the price of the print service is charged by being added to the call charge of the portable terminal 100.

[0121] The service provider charges with the user the service charge as the price of the print service, added to the call charge, thereby obtaining the price of the service.

[0122] If the user inputs, as the various information associated with printing, a desired service area which is the approximate location where the service of output data is desired, desired service area data indicating the desired service area is transmitted to the data output control terminal 300. On the data output control terminal 300, A search is performed on the printing apparatus position data in the storage apparatus 62 based on the obtained desired service area data, selecting all the printing apparatuses PR in the area identified by the desired service area data.

[0123] For example, if the user inputs “Shibuya” as the desired service area, on the portable terminal 100, all the printing apparatuses PR provided in the proximity of Shibuya are displayed on the LCD 44.

[0124] If the user inputs the print specifications of the printing apparatus PR as the various information associated with printing, print specification data indicating the print specifications is transmitted to the data output control terminal 300. On the data output control terminal 300, a search is performed on the print specification data in the storage apparatus 62 based on the obtained print specification data, selecting all the printing apparatuses PR which comply with the print specification data.

[0125] For example, if the user inputs “color” as the print specifications, on the portable terminal 100, all the printing apparatuses which allow printing of data in color are displayed on the LCD 44.

[0126] If the user inputs data format as the various information associated with printing, print format data indicating the data format is transmitted to the data output control terminal 300. On the data output control terminal 300, a search is performed on the print format data in the storage apparatus 62 based on the obtained print format data, selecting all the printing apparatuses PR which comply with the print format data.

[0127] For example, if the user inputs “HTML format” as the data format, on the portable terminal 100, all the printing apparatuses PR corresponding to a data-format-conversion terminal CS which allows conversion of data in HTML format are displayed on the LCD 44.

[0128] If the user inputs a printing apparatus ID of the printing apparatus PR as the various information associated with printing in order to directly specify the printing apparatus PR, printing-apparatus identification data indicating the printing apparatus ID is transmitted to the data output control terminal 300. On the data output control terminal 300, a search is performed on the printing apparatus data in the storage apparatus 62 based on the obtained printing-apparatus identification data, selecting the printing apparatus PR corresponding to the printing-apparatus identification data.

[0129] For example, if the user inputs “0001” as the printing apparatus ID, on the portable terminal 100, a printing apparatus PR whose printing apparatus ID is “0001” is displayed on the LCD 44. If a printing apparatus PR whose printing apparatus ID is “0001” does not exist, no printing apparatus PR is displayed.

[0130] If the user inputs the desired service area, the print specifications, and the data format compositely as the various information associated with printing, data indicating them is transmitted to the data output control terminal 300. On the data output control terminal 300, a search is performed based on the obtained plurality of data, and selecting all the printing apparatuses PR in accordance therewith.

[0131] For example, if the user inputs “Shibuya”, “color”, and “HTML format” as the desired service area, the print specifications, and the data format, on the portable terminal 100, of the printing apparatuses PR corresponding to the data-format-conversion terminal CS which allows conversion of data in HTML format, all the printing apparatuses provided in the proximity of Shibuya and which allow printing of data in color are displayed on the LCD 44.

[0132] If the user is not a legitimate user of the print service provided by the data output control terminal 300, when the image is displayed on the LCD 44, even if a selection that the printing data to be printed is actually the image displayed on the LCD 44 is input via the key panel 40, the desired data is not printed by the printing apparatus PR₁.

[0133] Thus, in the embodiment, the data output control terminal 300 selects one of the printing apparatuses PR₁ to PR_(n) from printing apparatuses PR corresponding to a data-format-conversion terminal CS which allows conversion of the data associated with the data print request; outputs the data associated with the data print request to a data-format-conversion terminal CS, of the data-format-conversion terminals CS which execute data-format-conversion processes, which allows conversion of the data and which corresponds to the selected printing apparatus PR; by the data-format-conversion terminal CS, converts the data associated with the data print request into data which can be printed by the selected printing apparatus PR; and outputs the converted data to the selected printing apparatus PR.

[0134] Thus, detailed information on the Internet 400 can be readily obtained compared with before. In particular, even if an output terminal is newly provided, setting of the data conversion means needs to be changed by the service provider only in relation to the new output terminal, allowing the new output terminal to be used without any change in setting by the user. Accordingly, the service provider will receive the advantages that setting works for newly provided output terminals are facilitated and that an information service with an adequate satisfaction can be provided to the user.

[0135] Furthermore, in the embodiment, with regard to the data-format-conversion terminals CS₁ to CS₁, one or more of the data-format-conversion terminals CS₁ to CS₁ is selected, so that the data-format-conversion processes are executed on the selected data-format-conversion terminals CS.

[0136] Thus, because the data-format-conversion processes are executed on data-format-conversion terminals CS with which the transmission load of the Internet 400 or the processing load is low, irrespective of the transmission load of the Internet 400 or the processing load of the data-format-conversion terminals CS, the time required to receive the service of output data is substantially constant. Accordingly, the service provider is allowed to provide to the user a print service with an even more comfortable printing environment.

[0137] Furthermore, in the embodiment, the data output control terminal 300 transmits preview data generated by a data-format-conversion terminal CS, and when a data print execution request from the portable terminal 100 is received as a response to the output of the preview data, it outputs data associated with the data print request to a printing apparatus PR.

[0138] Thus, by notifying the user of the preview data prior to the service of output data, the user is prevented from printing wrong data. Accordingly, the service provider is allowed to provide to the user an even more satisfactory information service.

[0139] Furthermore, in the embodiment, the data-format-conversion terminals CS₁ to CS₁ generates preview data in accordance with the display functionality of each type of the portable terminal 100.

[0140] Thus, an optimal image is displayed on the portable terminal 100 in accordance with the display functionality, allowing the user to grasp rather accurately an image of the data associated with the data print request as printed by the printing apparatus PR. Thus, the user is further prevented from printing wrong data. Accordingly, the service provider is allowed to provide to the user an even more satisfactory information service.

[0141] Furthermore, in the embodiment, the data output control terminal 300 obtains data associated with a data print request from a WWW server DS.

[0142] Thus, when detailed information is printed, the data output control terminal 300 processes print data and data which can be printed by the printing apparatus PR, eliminating the need for an expanded memory on the portable terminal 100 and reducing the processing load of the portable terminal 100. Furthermore, since the portable terminal 100 need not read data, the communications time is reduced, thus reducing the time required for receiving output data. Accordingly, the service provider is allowed to provide to the user a print service with a comfortable printing environment which is independent of the functionality of the portable terminal 100.

[0143] Furthermore, in the embodiment, the data output control terminal 300 selects one of a plurality of printing apparatuses PR based on portable-terminal-position data for identifying the position of the portable terminal 100.

[0144] Thus, data is printed by a printing apparatus PR in relation to the position of the portable terminal 100. Thus, for example, by selecting a printing apparatus PR which is presumably nearest, in terms of distance or time, with reference to the position of the portable terminal 100, the user is allowed to receive output data more easily, obtaining detailed information on the Internet 400 even more easily. Accordingly, the service provider is allowed to provide to the user an even more satisfactory information service.

[0145] Furthermore, in the embodiment, the data output control terminal 300 obtains data from a WWW server identified by a URL included in a data print request.

[0146] Thus, detailed information on any WWW server DS connected to the Internet 400 is allowed to be obtained. Accordingly, the service provider is allowed to provide to the user an even more satisfactory information service.

[0147] Furthermore, in the embodiment, the data output control terminal 300 obtains from a WWW server DS print data as data associated with a data print request.

[0148] Thus, rough information is displayed on the portable terminal 100 and detailed information is printed by the printing apparatus PR, thus allowing the portable terminal 100 to obtain detailed information on the Internet 400 while achieving a comfortable display processing. Accordingly, the service provider is allowed to provide to the user an even more satisfactory information service, and a print service with an even more comfortable printing environment.

[0149] Furthermore, in the embodiment, the data output control terminal 300 executes billing in accordance with the result of use by the portable terminal 100 of the print service provided by the data output control terminal 300.

[0150] Thus, the service charge as the price of the print service can be specifically calculated, and the service charge need not be calculated each time the print service is used. Thus, the procedure of settling the service charge is facilitated, and the service charge can be specifically notified to the user; accordingly, the service provider is allowed to provide an even more satisfactory information service.

[0151] Furthermore, in the embodiment, the service charge as the price of the print service is summed with the call charge.

[0152] Accordingly, for the user, payment of the service charge is facilitated; for the service provider, collection of the service charge will be easier and more secure, and the procedure of settling the service charge is further facilitated.

[0153] Furthermore, in the embodiment, the data output control terminal 300 transmits to the portable terminal 100 guide data indicating guide information for guiding the user from the position of the portable terminal 100 to the position where the determined printing apparatus PR is provided.

[0154] Thus, the user is allowed to visit, according to the guide information, the position where the printing apparatus PR is provided, thus obtaining output data relatively securely. Accordingly, the service provider is allowed to provide to the user an even more satisfactory information service.

[0155] In the above-described embodiment, the printing apparatuses PR correspond to the output terminals in claims 1 to 3, or 6, the data-format-conversion terminals CS₁ to CS₁ correspond to the data conversion means in claims 1 to 5, and to the image data generating means in claim 6, step S204 corresponds to the selecting means in claims 1 to 3, or 6, step S226 corresponds to the output means in claims 1 to 3, and steps S216 and S226 correspond to the output means in claim 6.

[0156] Also, in the above-described embodiment, the printing apparatuses PR correspond to the output terminals in claims 7 to 9, the data-format-conversion terminals CS₁ to CS₁ correspond to the data conversion means in claims 7 to 11, step S204 corresponds to the selecting means in claims 7 to 9, and step S226 corresponds to the output means in claims 7 to 9.

[0157] In the above-described embodiment, the arrangement is such that as printing apparatuses PR which are presumably the most suitable for the user of the portable terminal 100 to receive the service of output data, printing apparatuses PR which are presumably nearest, in terms of distance or time, with reference to the position of the portable terminal, printing apparatuses PR in an area identified by desired service area data, printing apparatuses PR which comply with print format data, printing apparatuses PR which comply with print specification data, or a printing apparatus PR corresponding to printing-apparatus identification data are selected; however, without limitation thereto, in addition, for example, printing apparatuses PR which presumably allow the user to receive the service of output data quickest in time with considerations to the output rates of the printing apparatuses PR, or printing apparatuses PR which provide the service of output data at the cheapest price may be selected.

[0158] In the former arrangement, because data associated with a data print request is printed by a printing apparatus PR which presumably allows the user to receive the service of output data quickest in time, the user receives the service of output data in accordance with his purpose, thus being allowed to readily obtain detailed information on the Internet 400.

[0159] In the latter arrangement, because data associated with a data print request is printed by a printing apparatus PR which provides the service of output data at the cheapest price, the user is allowed to receive the service of output data in accordance with his purpose, thus being allowed to readily obtain detailed information on the Internet 400. Accordingly, the service provider is allowed to provide to the user an even more satisfactory information service.

[0160] Furthermore, in the above-described embodiment, the arrangement is such that the printing apparatuses PR₁ to PR_(n) for printing data are provided, data associated with a data print request from the portable terminal 100 being printed by one of the printing apparatuses PR; however, without limitation thereto, for example, the arrangement may be such that output apparatuses which displays data or outputs data as sound, etc. are provided, data associated with a data output request from the portable terminal 100 being output by one of the output apparatuses.

[0161] Furthermore, in the above-described embodiment, the arrangement is such that preview data is generated by the data-format-conversion terminals CS; however, without limitation thereto, the arrangement may be such that the preview data is generated by the data output control terminal 300.

[0162] Furthermore, in the above-described embodiment, with regard to the data-format-conversion terminals CS₁ to CS₁, the arrangement is such that one or more of the data-format-conversion terminals CS₁ to CS₁ is selected in accordance with the transmission load of the Internet 400 or the processing load of the dataformat-conversion terminals CS, the data-format-conversion processes being executed by the selected data-format-conversion terminals CS; however, without limitation thereto, the arrangement may be such that the data-format-conversion processes are executed by a specific data-format-conversion terminal.

[0163] Furthermore, in the above-described embodiment, the arrangement is such that the processes shown in the flowcharts of FIG. 5 and FIG. 7 are executed by a specific data output control terminal 300; however, without limitation thereto, the arrangement may be such that, similarly to the data-format-conversion terminals CS₁ to CS₁, a plurality of data output control terminals is provided, and one of the plurality of data output control terminals is selected in accordance with the transmission load of the Internet 400 or the processing load of the data output control terminals, the processes being executed by the selected data output control terminal.

[0164] In accordance with the arrangement, because the processes shown in the flowcharts of FIG. 5 and FIG. 7 are executed by a data output control terminal with which the transmission load of the Internet 400 or the processing load is low, irrespective of the transmission load of the Internet 400 or the processing load of the data output control terminals, the time required to receive the service of output data is substantially constant. Accordingly, the service provider is allowed to provide to the user a printing service with an even more comfortable printing environment.

[0165] Furthermore, in the above-described embodiment, the description deals with a case in which a data output control apparatus according to the present invention is applied with the Internet 400; however, without limitation thereto, it may be applied with networks other than the Internet 400.

[0166] Furthermore, in the above-described embodiment, the portable terminal 100, the data-format-conversion terminals CS₁ to CS₁, the WWW servers DS₁ to DS_(m), the printing apparatuses PR₁ to PR_(n), and the data output control terminal 300 are connected via the same network; however, without limitation thereto, the data output control terminal 300 and the portable terminal 100, the data output control terminal 300 and the data-format-conversion terminals CS₁ to CS₁, the data output control terminal 300 and the WWW servers DS₁ to DS_(m), and the data output control terminal 300 and the printing apparatuses PR₁ to PR_(n) may be respectively connected via different networks.

[0167] Furthermore, in the above-described embodiment, the description deals with a case where the processes shown in the flowcharts of FIG. 5 and FIG. 7 are executed by executing the control programs stored, in advance, in the ROMs 32 and 52; however, without limitation thereto, the programs to be executed may be read into the RAMs 34 and 54 from a storage medium storing the programs showing the procedures.
